Secretary of State Rex Tillerson says the U.S. doesn't want to take military action against North Korea, but "all of the options are on the table" if a serious threat arises. Tillerson made his frank remarks in a visit to South Korea on Friday, a day after saying diplomatic efforts "have failed" to persuade North Korea to abandon its nuclear program.

Tillerson's Asia tour began in Japan and will end in China. The top American diplomat is traveling without a press contingent.

South Korean defense officials and the U.S. Strategic Command say North Korea test-fired a "medium- or intermediate-range" ballistic missile early Sunday morning local time, which flew eastward for about 300 miles from the west coast of North Korea, over the peninsula and landed in the Sea of Japan. This marks the first missile test by the Kim Jong Un regime since October, and the first during the new Donald Trump presidency.
